I would like to add that harlots also bring bastards into the world, which is abominable before God, and commit pedophilia on them by breast feeding. More reason that God commands us to burn pregnant harlots.

Genesis 38:24 Tamar thy daughter in law hath played the harlot; and also, behold, she is with child by whoredom. And Judah said, Bring her forth, and let her be burnt.

Deuteronomy 23:2 (King James Version) 2A bastard shall not enter into the congregation of the LORD; even to his tenth generation shall he not enter into the congregation of the LORD.
